Research And Application Of Digital Journey Mobile Services Mode Of G/S

The paper has designed a theoretical model of spatial information Services ,describes a model of daily life information. According to the model, people consume Services by the spatial information Services platform(such as Ustar, Google Earth, etc.). These Services will be provided in the form of network aggregation. Nodes can be connected by Mushup, SOA, XML, Web Services and so on, which Services to each other by these connection. With the development of digital city, 3G wireless networks and system network, people living in future will enjoy the a ubiquitous information environment, who can create, access, obtain and share information and knowledge freely. And with the information technology integrate into people's life, information technology supports the political, economic, social and cultural development completely .The model of G/S is a comprehensive information Services model, which has combined with spatial information technology, computer network, multimedia, virtual reality, and massive data processing technology and so on. G/S model bring about the massive earth science data to Services the public. According to the form of geo-information browser, the model of G/S can be divided into the Digital Earth Platform Mode PC-based and the Spatial Information Mobile Services Mode based on mobile terminals. the Spatial Information Mobile Services Mode is the supplement of the Digital Earth Platform Mode, which extends the application area of G/S Model. the Digital Earth Platform Mode has good performance of Three-dimensional display and support the complex HGML and so on. At the same time, people are born with mobility which is the biggest advantage of the Spatial Information Mobile Services Mode either. And the Services connect people ,space-time and digital world together, which extend to the people's daily life.Through studying the feature of the space-time and the mobile of the real world, this paper figures out the method of Services everywhere, further propounds the Spatial Information Mobile Services Mode which indicates a reference model for spatial information Services system.This paper analyzes the status of spatial information technology's development, and demonstrates necessity and feasibility about the resource integration Services, and figures out the Services model in the mobile environment. The main research work as follows: (1) In-depth research of the system architecture, the technical architecture and the method of data organization and transmission of the Spatial Information Mobile Services Mode of G/S, this paper designs a spatial information mobile services platform based on G/S model.(2) Design HGML file sharing subsystems, through the internet web server, which bringed about the share of diagrams of tourist routes.(3) Through research of Web Services, SOA architecture, Mashup, and the method of aggregation Services by the spatial information mobile Services platform, this paper figures out of the system architecture of the consumer services and the method of aggregation services on the spatial information mobile services platform.Finally research into implementation steps and practicality of the Spatial Information Mobile Services Mode. design a JiuZhaiGou digital tourism system base on the mobile terminal of Android and Blackburry.
